Grey's Anatomy has 12 seasons on Netflix and the 13th season is currently being streamed weekly on TV. Throughout the series many of the main characters remain in the show, but occasionally the Surgeons move to other hospitals or pass away from a catastrophic event. There is a lot of tragedy that takes place over the course of the show as we learn about the death of many patients and even the death of loved characters.
I have been watching Grey's Anatomy for about a year. I watch approximately 3 episodes per week. I usually watch this show before I go to bed or on the weekends. I enjoy washing this show because there is always something new going on at the hospital. There is always a new patient the surgeons are working on and new drama playing out between the characters. Each character at the hospital as a distinct personality and creates diffenrt relationship with the others that work there. I would defiantly recommend watching this series. Even though there are many seasons, it is defiantly worth it.
